1SSI
4.1 Product Overview
• Fast mode can be selected; with rapid encoder value detection and compressed
• Maximum encoder sampling rate (e.g., for ultrasonic encoders) is taken into account in
• Sign of life in isochrone mode
• Parity check of encoder value can be performed
• Gray/dual converter
Supported Encoder Types
The following encoder types are supported:
• Absolute encoder (SSI) with 13 bits
• Absolute encoder (SSI) with 14 bits
• Absolute encoder (SSI) with 16 bits
• Absolute encoder (SSI) with 21 bits
• Absolute encoder (SSI) with 24 bits
• Absolute encoder (SSI) with 25 bits
Firmware update
1
To add functions and for troubleshooting, it is possible to load firmware updates to the
operating system memory of the 1SSI using STEP 7 HW Config.
Note
Notice!
When you start the firmware update, the old firmware is deleted. If the firmware update is
interrupted or canceled for any reason, the 1SSI will no longer function correctly as a result.
Re-launch the firmware update and wait until this has completed successfully. See also ET
200S Distributed I/O System Manual, section: Identification Data.
